I have purchased a "spare" 3HM35F and it is sitting in my garage. I have some old AGM batteries which used to be rated for 75Ahs. They currently only test at about 6Ahs. Since they were sitting around waiting for disposal I grabbed one and hooked it up. It started the engine without a problem. Keeping in mind that it isn't a "good" battery, it was only able to crank the engine for a total of about 45 seconds. I think that one of those lithium batteries at 18Ahs would probably get you a minimum of about 3 minutes of crank time which should be more than enough.
I'll tell you what, I'll do the testing if someone else provides the battery. ;-) Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Dec 1, 2015 7:43 AM, "Richard N.
